SOFAR SF-5KWH-L1 is a low-voltage battery module with a capacity of 5.12 kWh, designed for residential energy storage systems. The battery uses safe and durable LiFePO₄ (LFP) technology, operates at a rated voltage of 51.2 V and provides 4.608 kWh of usable energy.

The SF-5KWH-L1 provides a rated charging and discharging power of 2.56 kW. The integrated intelligent BMS monitors cell voltage, current and temperature, balances the cells and provides protection against overcharging, over-discharging, overcurrent and excessively high or low temperatures.

One of the key features of the SF-5KWH-L1 is its flexible installation design. Its 19-inch standard construction allows the module to be installed on a wall, on the floor or in a standard 19-inch rack cabinet. In floor-mounted installations, multiple modules can be stacked using dedicated brackets, creating a compact energy storage system adapted to the available space.

The system allows up to 16 modules to be connected in parallel, increasing the total energy storage capacity to approximately 81 kWh. Automatic module addressing simplifies the configuration of larger systems, while CAN communication enables data exchange between batteries and communication between the BMS and a compatible inverter.
